Effect of Huanglian Decoction on the Intestinal Microbiome in Stress Ulcer (SU) Mice

Figure 6

The Shannon index curve. The horizontal axis represents the different sequencing depths of the sample, and the vertical axis represents the Shannon index at the corresponding depth. The curves of different colors represent the Shannon curves of different samples. The curve increases until it is smooth, indicating that the sequencing depth is enough to cover most of the microorganisms in the sample.
